Mokhoa oa ts'ebetso oa Redispersible Polymer Powder (RDP) ka seretse se omileng

Redispersible Polymer Powder(RDP)ke tlatsetso ea bohlokoa mefuteng ea seretse se omeletseng, e fanang ka melemo e mengata joalo ka ho khomarela hantle, momahano, ho tenyetseha le ho sebetsa. Mokhoa oa eona oa ts'ebetso o kenyelletsa mekhahlelo e mengata, ho tloha ho hasana ka metsing ho ea ho sebelisana le likarolo tse ling ka har'a motsoako oa seretse. A re ke re hlahlobeng mokhoa o qaqileng:

Phasano ka Metsing:
Likaroloana tsa RDP li etselitsoe ho hasana ka potlako le ka mokhoa o ts'oanang metsing ka lebaka la tlhaho ea tsona ea hydrophilic. Holim'a metsi ho motsoako o omileng oa seretse, likaroloana tsena lia ruruha le ho hasana, li etsa ho fanyeha ho tsitsitseng ha colloidal. Ts'ebetso ena ea ho hasana e pepesa sebaka se seholo sa polymer ho tikoloho e potolohileng, ho nolofatsa litšebelisano tse latelang.

Tlhahiso ea lifilimi:
Ha metsi a ntse a tsoela pele ho kenngoa ka har'a motsoako oa seretse, likaroloana tsa RDP tse qhalakaneng li qala ho phalla, ho etsa filimi e tsoelang pele ho pota-potile likaroloana tsa cementitious le likarolo tse ling. Filimi ena e sebetsa e le tšitiso, e thibela ho kopana ka ho toba pakeng tsa lisebelisoa tsa cementitious le mongobo o ka ntle. Sena se bohlokoa bakeng sa ho fokotsa ho kenella ha metsi, ho matlafatsa nako e telele, le ho fokotsa kotsi ea efflorescence le mefuta e meng ea ho senyeha.

Kamano e Matlafalitsoeng le Momahano:
Filimi ea polymer e entsoeng ke RDP e sebetsa e le moemeli oa tlamahano, e khothalletsang ho khomarela pakeng tsa seretse le likaroloana tse sa tšoaneng tse kang konkreite, masonry kapa lithaele. Filimi e boetse e ntlafatsa momahano ka har'a matrix a seretse ka ho koala likheo pakeng tsa likaroloana, kahoo ho matlafatsa matla a kakaretso le botšepehi ba seretse se thata.

Flexibility le Crack Resistance:
O mong oa melemo ea bohlokoa ea RDP ke bokhoni ba eona ba ho fana ka maemo a bonolo ho matrix a seretse. Filimi ea polymer e amohela metsamao e nyane ea substrate le ho atolosoa ha mocheso, ho fokotsa kotsi ea ho phatloha. Ho feta moo, DPP e ntlafatsa matla le ho tsitsa ha seretse, ho ntlafatsa ho hanyetsa ha eona ho robeha tlas'a meroalo e tsitsitseng le e matla.

Paballo ea Metsi:
Boteng ba RDP ka har'a motsoako oa seretse se thusa ho laola ho bolokoa ha metsi, ho thibela ho fetoha mouoane ka potlako nakong ea pele ea ho folisa. Nako ena e atolositsoeng ea hydration e khothalletsa hydration e feletseng ea samente 'me e tiisa tsoelo-pele e nepahetseng ea thepa ea mechine, e kang matla a khatello le a flexural. Ho feta moo, ho boloka metsi a laoloang ho kenya letsoho ho ntlafatseng ts'ebetso le nako e telele e bulehileng, ho nolofatsa ts'ebeliso e bonolo le ho phethoa ha seretse.

Ntlafatso ea ho tšoarella:
Ka ho ntlafatsa ho khomarela, ho tenyetseha, le ho hanyetsa ho phunyeha, DPP e ntlafatsa haholo ho tšoarella ha lisebelisoa tsa seretse se omileng. Filimi ea polymer e sebetsa e le tšitiso e sireletsang khahlanong le ho kenella ha mongobo, litlhaselo tsa lik'hemik'hale, le litšila tse silafatsang tikoloho, ka tsela eo e lelefatsa bophelo ba tšebeletso ea seretse le ho fokotsa litlhoko tsa tlhokomelo.

Ho lumellana le li-Additives:
RDPe bonts'a tšebelisano e ntle haholo le li-additives tse fapaneng tse atisang ho sebelisoa ha ho etsoa seretse se omeletseng, joalo ka li-intrainer tsa moea, li-accelerator, li-retarders le li-pigments. Mokhoa ona oa ho feto-fetoha o lumella ho etsoa ha thepa ea seretse ho fihlela litlhoko tse khethehileng tsa ts'ebetso bakeng sa lits'ebetso tse fapaneng le maemo a tikoloho.

mokhoa oa ts'ebetso ea phofo ea polymer e qhalakaneng ka seretse se omeletseng e kenyelletsa ho hasana ka metsing, sebopeho sa filimi, ho khomarela ho matlafatsa le ho momahano, ho feto-fetoha ha maemo le ho hanyetsa ho phatloha, ho boloka metsi, ho matlafatsa nako e telele, le ho lumellana le li-additives. Liphello tsena tse kopantsoeng li kenya letsoho mosebetsing o ntlafetseng, ho sebetsa, le ho tšoarella ha litsamaiso tsa seretse se omeletseng ho pholletsa le mefuta e mengata ea kaho.
